13 Claims.

This invention relates to improvements in cash registers, and is more particularly directed to improvement for machines of the type illustrated and described in Letters Patent of the United States 1,658,993 granted to Leo G. A. Kommling on February 14, 1928, which latter patent shows improvements in stopping and releasing mechanisms for machines of the type shown and described in Letters Patent of the United States 1,506,260, issued to B. M. Shipley on August 26, 1924.

Briefly the subject matter of the Kommling patent above mentioned relates to a cash register in which the cycle of operation is subdivided into two portions, each being released by a separate motor bar. Such arrangement works in such a way that the machine is locked after it has run through a portion of a full cycle of operation and is again released by depressing a second motor bar, so that the last portion of the cycle may be completed.

' A mechanism having those functions is very important and also very useful in connection with systems which require printing on two forms, wherein the printed impressions are to be made on a different line during one operation of the machine, since it permits the operator to shift the carriage carrying the form after the machine has made the first impression and prior to the time of making the second impression so that the second impression may be printed upon a different line than that of the first impression.

It may occur however in certain cases such for instance, as at the end of the day when the balance is to be taken that only one impression is necessary. In such cases the interruption of the cycle of operation, or in other words, the locking of the machine during the cycle, is not desired.

It is, therefore, an object of the present invention to provide mechanism so connected with the releasing mechanism and the printing mechanism of the machine that when the machine is released by the operation of one of the motor bars, the machine will run through its complete cycle of operation without any interruption provided the operator first operates a special key which not only renders the locking mechanism intermediate the cycle of operation ineffective but also controls the printing device so that only one impression is made.

With these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Of said drawings:

Fig. 1 is a left side view of the auxiliary releasing mechanism, and also shows the special key for controlling the machine stopping mechanism and the printing mechanism.

Fig. 2 is a detail view of the main motor bar releasing mechanism.

Fig. 3 is a detail view of the impression mechanism.

Fig. 4 is fragmentary portion of one of the ledger cards.

Fig. 5 is a detail fragmentary view of a second ledger card, and shows the printing on this card as having been made on different lines from that on the card shown in Fig. 4.

GENERAL DESCRIPTION The machine to which the invention is shown attached is used for printing duplicate records on two cards during one cycle of operation of the machine. The cards are inserted in a movable carriage for selecting the lines upon which the data are to be printed, but the positions of the corresponding items on the two cards may vary; for example, the items entered may be printed on line 1, on one card, and on line 5 on the second card, because the fifth line is the first blank line on the second card. Such a machine is shown in the above mentioned Kommling Patent 1,658,993.

In order to print on different lines on each card as provided herein, it is necessary to provide an automatic means for stopping the machine during the cycle of operation after the first impression has been made, so that the carriage can be shifted to cause an impression to be made on the desired line on the second card during the latter part of the same cycle. To accomplish this a means is provided for actuating the usual stopping device for stopping the machine and an auxiliary motor bar is provided near the left end of the machine for releasing the machine after the carriage has been readjusted so that the machine can complete its cycle of operation.

During total-taking operations, as is customary in machines of the type referred to above, the machine makes two cycles of operation; but, as is also customary, during the first cycle the printing mechanism is ineffective. For this reason a device fully illustrated and described in the above mentioned Kommling patent has been provided for disabling the stopping device so that the machine will not be stopped until after the first impression has been made which, during total-taking, is during the second cycle of operation.

As previously stated, it may occur that in certain cases, such as, when the balance of the day is taken, only one imprint is necessary and during such balance clearing operation the interrupting of the cycle, or locking of the machine,

during such cycle of operation is not desirable. Therefore, a special key known in the art as a non-print key, and illustrated in the Shipley Patent 1,619,796 granted on March 1, 1927, and also the Shipley Patent 1,628,336 granted May 10, 1927, has been utilized to control the machine so that the cycle of operation will not be interrupted whenever this key is depressed. This special key also has been arranged to control the printing mechanism which prints upon the two cards illustrated in Figs. 4 and 5.

In the last two Shipley patents mentioned the so-called non-print key has been shown as con trolling the check or receipt printing mechanism, whereas in the present case, as above mentioned, the mechanism in connection with this key is so arranged that the usual lower or slip printing impression mechanism is controlled thereby.

DETAILED DESCRIPTION Only so much of the mechanism of machines of the type illustrated and described in all of the above mentioned patents will be shown and described herein as is necessary to fully illustrate and explain the present invention. For more detailed description of the types of machines referred to, attention is directed to such patents mentioned and also a Shipley Patent 1,761,542

- granted on June 3, 1930, which patent fully illustrates and describes the type of printing carriage for supporting the ledger card, and in connection with which there is a line selecting mechanism whereby the operator can readily select the line upon which it is desired to have the printing impression made.

Driving mechanism When the machine is operated by means of an electric motor, the usual well-known clutch mechanism is provided, a portion of which is shown in Fig. 1. For a detailed description of this clutch mechanism reference to be had to the last mentioned Shipley Patent 1,761,542. This type of motor clutch is also fully illustrated and described in the United States Letters Patent to Charles F. Kettering and W. A. Chryst 1,144,418, granted on June 29, 1915.

r The clutch is provided with the usual disk (Fig. 1) adapted to wedge rollers 31 carried by a disk 32 between the disk 30 and a clutch memher not shown herein. The disk 30 is secured to a pinion (not shown) which meshes with a gear 34 which in turn meshes with a gear 35 secured to a main cam shaft 36. When the clutch is released for effective operation, the motor will turn the cam shaft 36 one complete rotation for item entering operations, and two complete rotations for total-taking operations. When it is desired to operate the machine manually, the usual handle (not shown) is provided and is connected by means of a suitable gearing to the main cam shaft 36. Such manual driving mechanism is very well known in this art, and it is, therefore, not shown herein.

Main motor bar The machine is provided with the usual release shaft 40 (Fig. 2) which controls the releasing of the machine when a main motor bar 41 is depressed. A spring (not shown) normally tends to rock the release shaft 40 in a clockwise direction.

Secured to this shaft 40 is an arm 53 having a flattened stud which normally engages a pawl 54 and prevents shaft 40 from rotating. When the motor bar 41 is depressed, the pawl 54 is raised, thereby permitting the shaft 40 to rock under the tension of the above mentioned spring. Depressing of the motor bar 40 will rock an arm 55 which is connected to an arm 56 by a pin and slot connection. This arm 56 is loosely mounted on a shaft 57 and is yoked to another arm 58 adapted to engage a stud 59 carried by an arm 60, which in turn is yoked to a bifurcated arm 61 connected to stud in the previously mentioned pawl 54. Thus, it is seen that when the motor bar 40 is depressed the pawl 54 is raised thereby permitting the previously mentioned spring (not shown) to rock the shaft 40 to release the machine.

The usual and well known non-repeat pawl 62 is provided which prevents a repeat operation of the machine, if the motor bar 33 is not permitted to return to the home position.

When the release shaft 40 is released by depressing of the motor bar 41 in the manner above described, an arm rocks counter-clockwise (Fig. 1). This arm '70 is secured to the shaft 40 and is provided with a curved finger 71 which normally engages a stud 72 carried by an arm 73 pivoted on a stud 69 carried by the side frame 68. A spring 74 tends to rock the arm 73 counter-clockwise, but is prevented from doing so by the curved finger 71 contacting the stud 72 in the arm 73. Also secured to the arm 73 is a stop arm 75 normally engaging a shoulder 76 on the previously mentioned disk 32. When the release shaft 40 is rotated the arm 70 is rocked from engagement with stud 72, thereby permitting the spring 74 to rock the stop arm 75 out of the path of the shoulder- 76 to permit rotation of the pinion (not shown) which is secured to the disk 32 so as to rotate the gear 34,

the gear 35 and consequently the operating impression has been taken on the top card, it

is ejected from the machine. Let it be assumed. that the first impression is to be made on the card shown in Fig. 4 and that this impression is to be made on the first line. When the card is inserted in the carriage, the carriage will be shifted to the appropriate position for printing on this line. After this impression has been made, and the top card is ejected, the machine will be automatically stopped by the stop arm 75, thereby permitting the operator to shift the carriage for printing on the second card, as for example, to the fifth line as shown in Fig. 5, so that the second impression will be made on the fifth line of the second card. The mechanism for stopping the machine aft 1' the first impression takes place will now be described.

Secured to the previously mentioned gear 34 (Fig. 1) is a roller 80 adapted to engage the lower end of a link 81, pivoted to the arm 73, after the first impression takes place. The link 81 is guided by stud 82 which projects through a slot in said link. When the roller 80 engages the lower end of the link 81, it raises the arm 73, thereby rocking the arm 75, secured thereto. into the path of a shoulder 83 on the previously mentioned disk 32, thus stopping the machine. The arm is held in position in the path of the shoulder 83 by means of a half round stud 84 secured on the upper end of a spring drawn lever 85. This lever is adapted to be rocked to position the half round stud 84 beneath shoulder 86 on the arm 73 when the latter is raised in the manner above described. The lever 85 is connected to a spring actuated lever 87 by a link 88. The lever 87 constantly tends to rotate in a clockwise direction due to a coil spring 89. one end of which bears against a stud 90 carried by the side frame 68 and the other end against the lever 87 as shown in Fig. 1. This lever 87 is normally held against rotation due to the fact that it contacts the roller 80. However, when the roller is moved far enough to raise the link 81 to cause the arm 75 to be rocked into the path of the shoulder 88, the lever 87 will be free to move thereby permitting the arm to rock to position the half round stud 84 beneath the shoulder 86 in the manner above mentioned.

After the machine is stopped during the cycle of operation and after the impression has been made on the first card, the operator can adjust the carriage to print upon any desired line of the second card. In order to again release the machine to permit it to complete its cycle of operation, it is necessary to provide an auxiliary motor bar, because at this time the main motor bar is ineffective for releasing the machine. This auxiliary motor bar 79 is carried by two studs 92 carried in a link 91 also guided by a stud 93. The lower end of the link 91 has a stud 94 which projects through a slot in the previously mentioned lever 87. Therefore, to release the machine so that it may complete its cycle of operation it is only necessary to depress the auxiliary motor bar 79, which, through the link 91 rocks the lever 87 counter-clockwise, whereupon the link 88 rocks the lever 85 counter-clockwise thus removing the stud 84 from beneath the shoulder 86. When this stud 84 is removed from beneath the shoulder on the arm 73 the spring 74 again rocks the arms 73 and 75 counter-clockwise, thus releasing the clutch mechanism so that it may be driven by its motor to complete the cycle of operation. Near the end of the cycle of operation, a stud 95, also carried by the gear 34 raises the link 81 and rocks the arms 73 and 75 so that the arm 75 will be positioned in the path of the shoulder 76 to positively stop the machine at the end of the completion of its cycle of operation.

Printing mechanism Since the printing mechanism for the types of machines to which the present invention has been applied are fully and clearly illustrated in the above mentioned Shipley patent only a brief description of the printing mechanism will be given herein as follows.

Referring particularly to Fig. 3, the printer drive shaft has been indicated by the reference letter 100. This shaft receives its motion by mechanism not herein shown but fully shown in the above mentioned Shipley Patent No. 1,619,796 so that it receives one complete rotation in a counter-clockwise direction upon each adding operation of the machine.

Type wheels 101 are adapted to be set according to the amounts which are set up on the keyboard during adding or item entering operations and also according to the amount of totals which are taken from totalizers during total-taking operations.

Cooperating with the type wheels, and especially in banking machines as illustrated in the Shipley Patent 1,761,542 are a series of platens 102 carried by hammers 103 pivoted on a shaft 104. Also pivoted on the shaft 104 adjacent to each hammer 103 is an arm 106 of a bell crank held against a stud 105 in the hammer 103 by a powerful spring 107. The bell crank arm 106 also has a finger 108 held against a yoke or bail 109, one arm of which is connected to an arm 110 carrying a stud 111 cooperating with a slot 112 in a link 113. The link 113 is pivoted to a bell crank 114 secured to a shaft 115. The bell crank 114 has a nose 116 adapted to cooperate with cam lobes 117 and 118 of a cam 119 secured to the printer shaft 100. The bell crank 114 also carries a roller 120 which is adapted to cooperate with the cam 119 and especially the camming edges of the lobes 117 and 118 to relieve the bell crank 114 of as much friction as possible. The arm 110 has a foot 121 held against a lug 122 on the base of the machine by the spring 107.

The cam 119 has an annular groove 130 with which cooperates the fork of an arm 131 secured to a shaft 132 (Figs. 1 and 3) for a purpose to be hereinafter described. By referring to Fig. 1 it will be noticed that the lobe 117 is only onehalf the width of the lobe 118. The purpose of this will be hereinafter explained.

The operation of the above mentioned printing mechanism is as follows. Upon counter-clockwise movement of the shaft 100 and cam 119 the bell crank 114, assuming that it is in the position shown in Fig. 1 wherein it is in alinernent with the wide lobe 118 only, is rocked in a clockwise direction by said lobe 118, thus drawing the link 113 toward the left as viewed in Fig. 3, whereupon the stud 111 rocks the arm 110 clockwise. This movement of the arm 110, through the yoke 109 rocks the bell crank arm 106 clockwise thus stretching the spring 107. The weight of the platen 102 and hammer 103 causes the stud 105 to follow the bell crank arm 106 as the latter is moved clockwise by the cam lobe 118. When the radial portion of the cam lobe 118 comes opposite the nose 116 the spring 107 rocks the above mentioned parts in the directions reverse to that just described, whereupon the bell crank arm 106 is rapidly and forcibly thrown in a counter-clockwise direction, and through the stud 105, the hammer 103 is moved likewise, whereupon the platen 102 strikes whatever printing medium is between it and the type wheel 101 to take an impression therefrom on such printing medium.

At certain times to be hereinafter described the cam 119 (Fig. l) is in a position right of that shown in this figure, whereupon both the lobes 117 and 118 cooperate with the bell crank 114. In such a case then of course the bell crank and hammer 103 receives two printing movements to cause two impressions to be made from the type Wheels 101.

Interrupted operation and printing control As stated at the outset of this specification it may at times be desirable to prevent the interruption of the operation of the machine and at Y the same time cause only one impression to be made from the type wheels 101 by the hammer 103.

First it might be well to state briefly how the shaft 132 is shifted toward the right as shown in Fig. 1 to bring both lobes 117 and 118 in alinement with the bell crank 114.

Cooperating with a cam race 140 in the gear 35 is the roller 141 carried by a pitman 142 slidab'zy guided by a stud 143 in the side frame 68. Pivoted to the pitman 142 is a lever 144 having a fiat surface 145 and a notch 146 adapted to cooperate with a stud 147 carried by the shaft 132. The cam race 140 is so constructed that it moves the pitman first toward the left whereby the lever 144 is drawn likewise toward the left until the pin 147 is opposite the notch 146, whereupon a spring 148 rocks the lever 144 counterclockwise which causes the notch 146 to engage the pin 147. This counter-clockwise movement of the lever 144 also rocks a latch 149, shown as engaging the pin 147, counter-clockwise to disconnect the same therefrom. Now, with the notch 146 engaging the pin 147 as the pitman 142 is moved toward the right, or in other words to the position shown in Fig. 1, the lever 144 will carry the shaft 132 toward the right, thus bringing the lobe 117 into cooperative alinement with the bell crank 114. Since the lobe 118 is twice the width of the lobe 117 this lobe 118 still remains in operative alinement with the bell crank 114. With the parts in such positions, upon movement of the shaft 100 (Fig. 3) two printing impressions are made from the type wheels 101.

The lever 144 has a finger 155 cooperating with a flange 156 and the bail 157 pivoted on a rod 158 carried by frames 159 and 160, for a purpose to be hereinafter described.

Interrupted operation control Should it be desirable to prevent the interruption of the operation of the mach ne, the operator depresses a key 160 which is held depressed by a latch (not shown) cooperating with a shoulder 161 in the manner fully illustrated and described in the Shipley Patents Nos. 1,619,796 and 1,628,336. When the key 156 is fully depressed its nose 161 is in the path of a stud 162 on the lever 85 and, therefore, when the link 81 is raised by the roller 86, which it will be remembered interrupts the operation of the machine by causing the stud 84 to pass beneath the shoulder 86 of the arm 83, will prevent any movement of the lever 85. Therefore, the stud 84 cannot be moved beneath the shoulder 86 and consequently the stop arm is not moved in the path of the shoulder 83 and the machine will complete its cycle without any interruption whatsoever.

Printer control At the same time the printing mechanism is controlled by the key 160 so that should the cam 119 be in a position whereby both the lobes 117 and 118 are in the operative alinement with the bell crank 114, said cam will be shifted so as to bring the lobe 117 out of operative alinement thus causing only one printing impression to be made by the hammer 103. The means under control of the key 160 for accomplishing the above result will now be described.

Pivoted on the stud 69 and connected to the key 160 is a lever 165, the other end of which is forked to cooperate with stud 166 on a lever 167 pivoted on a stud 168. Connected to the lever 167 is a link 169 the lower end of which is guided by a stud 170 in the frame 159. Depression of the key 160 rocks the lever 165 counter-clockwise which through the stud 166 rocks the lever 167 clockwise thus lowering the link 169 which positions a toe 171 of the link 169 in contact with the flange 156, assuming the flange to be in the position shown in Fig. 1, wherein it is in engagement with the finger 155 of the lever 144 and that the shaft 132 is in the position shown in Fig. 1. Now as the pitman 142 moves toward the left the lever 144 will not be rocked by its spring 148 when the notch reaches a position directly below the stud 147 due to the fact that the toe 171 of the link 169 maintains the flange 156 in contact with the finger 155 of the lever 144. Consequently the lever will slide toward the left and back to the position shown again but the notch 146 will not engage the stud 147 and the shaft 132 will remain in the position shown whereby the lobe 117 is not in operative alinement with the bell crank 114 and consequently only one imprint or printing impression will be made by the hammer 103.

Let us now assume that the shaft 132 has been previously moved toward the right as viewed in Fig. 1, whereupon the lug 117 is in operative alinement with the bell crank 114 to give two printing impressions. In such a case the lover 14.4 will have been rocked counter-clockwise until notch 146 is in engagement with stud 147 and the flange 156 would then be in the dot-and-dash line position 17 (Fig. 1) and the latch 149 would be disengaged from the stud 147 in the shaf 132. Now when the operator depresses the key 166 thus lowering the link 169, as previously described, then upon such lowering of the link the toe 171 would move the flange 156 downwardly and rock the lever 144 downwardly to the position shown in Fig. 1. So that upon the operation of the machine pitrnan 142 by its forward and backward movement would merely cause a sliding of the lever 144 and said lever 144 on its movement toward the left would carry the shaft 132 toward the left as viewed in Fig. 1, to bring the lobe 117 out of the path 01' the bell crank 114 so that only one impression would be made, wher as had the key 160 not been depressed then both the lobes 117 and 118 would have been in alinement with the bell crank 114 and two impressions would have been made.

From the above description it can therefore be clearly seen that the depression of the key 160 not only prevents the interruption of the operation of the machine by the roller and link 81, but also causes the printing mechanism to make one impression if it is not already in a position to one impression, by moving the cam 119 whereby only the lobe 118 will be in operative alinement with the printer operating bell crank 114.

A spring 173 connected between the latch 149 and lever 144 rocks the latch 149 clockwise when the pin 147 is moved beneath the same when the shaft 132 has been moved to the left to the position shown in Fig. 1. This spring also helps to maintain a stud 175 on the latch 149 in contact with the surface 145 of the lever 144.

A spring 174 connected to the stud 166 restores the link 169, lever 167, lever 165 and key 160 to their normal positions at the completion of the operation of the machine when the latch (not shown) is released from the shoulder 161 on the key 166 by the key releasing movement of the release shaft 40. This releasing movement of the release shaft is not described in this case nor is the mechanism for moving it in that direction shown herein, and reference may be had to the above mentioned Shipley patents for a full disclosure and description of such mechanism.

Total-taking operation As is well known in machines of this type, the main cam shaft 36 receives two complete rotations during total-taking operations. However, the printing is performed only during the second rotation of the shaft 36 and for this reason the printer shaft 100 is not operated during the first rotation of the shaft 36. The means for preventing the rotation of the shaft 100 during the first rotation of the shaft 36 is not shown or described herein as this mechanism is well known in this art and is fully illustrated and described in the above mentioned Shipley Patent 1,619,796.

In the Kommling Patent 1,658,993, above referred to there is mechanism provided for preventing the interrupting of the second cycle of operation of the total-taking operation. However, this mechanism does not in any way control the printing mechanism and two impressions are always made during the second cycle of a total-taking operation in the Kommling struc ture.

This structure as shown in the Kommling patent is under the control of the usual total lever in machines of this type and prevents any interruption of both cycles of the total-taking operation.

In the instant machine the depression of the key 160, due to the fact that it blocks any movement of the lever 85 in a clockwise direction as viewed in Fig. 1, also prevents any interruption of both cycles of a total-taking operation because this key remains depressed until near the end of the second cycle of a total-taking operation. This key mechanism therefore may or may not be used in connection with the structure operated and controlled by Kommling totaltaking lever. It can be seen from the above description that it is not entirely necessary to use all of this mechanism of Kommling which is controlled by the total-taking lever because this key 160 itself controls the machine so that neither of the two cycles of a total-taking operation will be interrupted when this key is in its depressed position.

Operation Since the movements of the parts have been quite clearly described during the description of the various groups of mechanisms only a general rsum of the functions of the machine will be given. As stated above this invention is used on the machines adapted to print data on different lines of two separate cards, both of which are inserted on a'carriage which is adjusted before the machine is released to print upon one of the cards. The machine is released by depressing the main motor bar 41 and it operates until the first printing operation has been completed at which time the first card is ejected and the machine is automatically stopped to enable the operator to manually adjust the carriage for printing on the second card, after which the auxiliary motor bar '79 is depressed for releasing the ma chine whereupon the machine completes the cycle of operation and the second impression is made upon the second card. If it is desirable to prevent any interruption of the cycle of operation the key 160 is depressed which by means of its stem being in the path of the stud 162 of the lever 85 prevents any locking of the arm '73 and the rocking arm and consequently the spring 74 immediately throws the arm 75 outwardly to allow the machine to complete its cycle of operation without any interruption whatsoever.

Depression of this key also, if the printing mechanism is in position to make two impressions upon the record material, causes the driving cam of the hammer to be shifted so that one impression will be made during the entire uninterrupted cycle of operation.

During total operations as previously stated the printing is performed during the second cycle of the operation but when the key 160 is depressed prior to the. taking of the total, both of the cycles of the total taking operation are run through without any interruption whatsoever and the machine then functions to make only one impression on whatever printing medium has been placed in the machine to receive that impression.
